I'd recommend staying at Vasu's place. The location was perfect - very near the BTS which makes it so convenient if you want to explore Bangkok. There are a number of vendors selling street food at the alley, and a 711 and Family Mart is just nearby. The condo unit is also quiet, which is perfect if you just want to stay in and rest, or do some work like I did. The building is also very secure, which is a plus for solo travelers like me. I'd definitely stay again at Vasu's place when I go back to Bangkok.
